MTA worker fired for collecting metrocards?

One man’s trash is another man’s treasure.  A New York City transit cleaner who collects discarded metrocards may be terminated from his job for using keys to open the metrocard litter boxes for his collection.  He was arrested when police spotted him opening the box. Do you think he should have been arrested?  The MTA says he wasn’t supposed to have the keys he claims he used for the lat 23 years to do his job.  Should he get his job back? What do you think?
